To (ll Ll irfzomit w: (13/ concern a ie it known that .l; CnAnLn: L. Athenian,

T .1. a citizen of the UnitedStates of America,

csicing Council Bluffs, in the county of ttawattaniie and State of Iowa, have invented certain new and useful Improvements in Inner Casings for Automobile-Tires, of which the following is a specification, refe'rencebeing had therein to the accompanying drawing, i i

' This invention for automobile tires and has foriit-s principal objectthe production of an inner lining which may be conveniently used on the inside of a pneumatic.tire-for prolonging the life thereof and protecting the inner tube, which is used in connection therewith, such inner lining being made of a combination of rubberized cords and fabric united togethenby vulcanizing so as to form a complete circle which will fit within difi'erent sized outer casings. k

' Another object of this invention is the production of an inner lining which iscoinposed of a plurallty of rubberized cords,

having wire reinforcements, thereby reinforcing the base of the lining, while transverse rubberized cords are interposed between the layers of the fabric, all of which are to 1 4 be united as to form a one-piece structure.

With these and other objects in view, this invention consists of bertain novel combinations'j constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a transverse section through a pneumatic the, showing the lining carried thereby as constructed in accordance with this invention. Fig. f is a longitudinal section of aportion of a pneumatic tire, showing the inner lining carried thereby partly broken away. Fig. 3 is a fragmentary sectional view through a portion of the pneumatic tire illustrating the base of the lining. Fig. i is a view similar to Fig. 3, illustrating the opposite side of a portion. of the tire and the inner casing shown in Fig. 3. Fig. 5

is a plan view of a portion of one of the longitiidinzil base cords. illustrating the manner in which the same is reinforced.

Referring to the accompanying drawing by numerals 1 designates the outer casing of a pneumatic tire which is'provide'd with the usual heels 2 which will facilitate the securing of the tire to the rim of a Wheel.

The lining comprises a plurali 1 S eld p w .ofrbase; cords 3 which are: pos t onedrs del by ,side

heel 2 of the tire 1. These cordsfi are res inforced by being woundi with,small-wires an l, such for instance as pianow since thecords 3 are also rubberized, they will form very strong and substantial bases adjacent each heel. The transverse cords 5 are also rubberized and extend in transverse relation to the central axis of the tire casing 1 and have their end portions engaging the hoops formed by the longitudinal cords 3 upon each side of the tire 1. These cords 5 are rubberized and will be greatly reinforced and will extend in transverse relation to the casing 1 so as to form a positive reinforcement therefor.

The outer fabric sheet 8 is passed around the outer portions of the transverse cords 5 and has its outer side edges lapped around the ends of the transverse cords 5 so as to terminate adjacent the bases of the hoops formed by the longitudinal base cords 3, as shown at 7. The inner fabric lining 6 is passed around the inner portions of the transverse cords 5 and has its outer side edges lapped over the folded or lapped portion 7 of the outer fabric sheet 6, as shown at 9, so as to bear against the inner portions of the pneumatic casing 1.

After the device has been assembled, as above set forth, it is vulcanized so as to form a one-piece structure which is capable of being placed within the inner portions of any pneumatic tire for forming a rein-'v 6 and 8 lapped -as hereinbefore set forth,

the-sheets will be positively retained in posi- .tion, independently of the vulcanizing process while by having'the ends terminating adjacent the hooks formed by the longitudinal cords 3, sufiicient space isfprovided for- .this folding or lapping act-ion.

From the foregoing description, it will be seen that a very simple and efficient inner lining has been producedfor pneumatic tires wherein the several elements are so positioned asto be readily assembled but which are adapted to be positively retained in engagement; with each other for forming a substantially one-piece structure. \Vhat I claim is In a lining for pneumatic tires, the combination of a plurality oftransversely extending cords positioned side by side, a plurality of longitudinally extending cords positioned 'side by side to form hoop-like structures, the

- end portions of said transversely extending cords engaging said hoop-like structures, an outer fabric sheet fitting upon the outer portions of said transversely extending cords, the portions of saidsheet adjacent the side edges thereof being bent so as to 'fit.

over the ends of said transversely extending cords and over said hoop-like structures, and an inner lining fitting upon the inner portions of said transversely extending cords, the portions'of said inner lining adjacent the side edges thereof being bent so;

as to overlap and fit upon the bent-over por tions of said'outer. fabric sheet, said cords,

sheets, and lining being adapted to be vulcanized together, the overlapped portions
